I would have seen him play in the early 1990s. A group of us guitar majors went together and I recall one of the grad students hated his playing because it was bright and at times brittle with tone thAt often broke up. Our teacher was more from the Segovia school and so many of us at that time felt his tone was unacceptable. In retrospect, I've come to appreciate that a brighter tone can facility faster playing and a clearer articulation were a dark tone can muddy the separation of fast notes. I don't remember the program, but it definitely had virtuosity in it, and Iznaola got the job done even if the tone was not what I cared for at the time.
